NB7M and its precursor 7Me-IEITC showed a striking similarity in the expression and/or activation of a multitude of molecular targets, including DNA-PK, Axl, PI-3K, Akt; the MAPKs ERK1/2, p38, JNK; NF- κB and the CDK inhibitor p27 (present manuscript; Singh et al, 2007; Brard et al, 2008; Singh et al, 2008).
NF-κB activation occurs for a multitude of cell stress and inflammatory signals that converge on the IKK (IκB Kinase) signaling hub, which induces degradation of the cytoplasmic inhibitor IκB and liberates NF-κB to enter the nucleus and regulate gene expression (Hayden and Ghosh, 2008).
